fragsmax New Member United States 42 Posts	Posted 03/15/2014 3:31 pm Hi All! Thank you in advance, again, for your assistance with this. I found this penny in a roll and am mystified as to what it is. It looks "grown", somewhat like ice might look on a window. It has limbs with leaf-like extensions. I've soaked it in Acetone for 2 days and nothing changed. Anybody seen this kind of thing before or have any idea what it might be? I think that it looks cool but don't know if it would have any value. Report this Post to the Staff

fragsmax New Member United States 42 Posts	Posted 03/15/2014 5:41 pm I wonder if it can be removed without causing further damage as this may be a die chip error coin. Report this Post to the Staff
kanga Pillar of the Community United States 5825 Posts	Posted 03/15/2014 7:58 pm It's verdigris. " Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates[1] or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride.[2] If acetic acid is present at the time of weathering, it may consist of copper(II) acetate. " Since the copper has been converted to one of the above mentioned compounds that would mean IF the verdigris was removed the copper would go with it. That would leave a telltale scar on the coin.
